About the only thing that will change the point gap is a bad bushing for the drive shaft. You will have rough idle and skips with a wobbling cam on the distributor. Take the rotor off and try to move the shaft side to side. If it does, the bushing is worn. You can get rebuilt dist reasonably, about $70 at NAPA or about $40 at O'Reilly.

If the shaft is tight, about the only thing you can do is keep working at it until the gap turns out right. It might be a non-flat base on the points if they are cheapies. The best thing you can do is install a Pertronix uhit with a proper coil. Others here Poo-poo it, but it does away with so many problems. If it fails, (which it rarely does if installed correctly) you can just reinstall your points and be on your way.
